BURNER FOR PETROLEUM GLOW-LAMPS.

SPECIFICATION forming part of Letters Patent N 0. 615,067, datedNovember 29, 1898. Application filed November 5, 1897- Serial No.657,503. (No model.)

To aZZ whom it may concern.-

Be it known that I, GEORG KRON, civil engineer, of Hejbergsgade 16,Copenhagen, Denmark, have invented certain new and useful Improvementsin Burners for Petroleum Incandescent Lamps; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to letters of reference marked thereon, which form a part of thisspecification.

This invention has relation to burners adapted for use withpetroleum-lamps producing a Bunsen flame, for the purpose of renderingincandescent the usual and wellknown mantle; and among the objects inview is to provide a burner whereby a steadilyburning Bunsen flamewithout smoke is produced, thus providing against the smoking orblackening of the mantle.

The invention consists in the novel construction, arrangement, andcombination of parts, as hereinafter fully described, illustrated in thedrawings, and pointed out in the appended claims.

In the drawings, Figures 1 and 2 are vertical sectional viewsillustrating different constructions of the invention.

The wick a is in a well-known manner inclosed in a wick-case formed bytwo concentric tubes. Above this is placed a cap d of such a shape thata narrow ring-shaped interval f is formed between the upper edge of thiscap and a central burner-disk e, the said interval being just above theupper end of the wick.

The purport of the invention is to cover the upper edge of the wickwit-h the uppermost bent edge 9 of a cap or casing h pushed over thewick-case. This arrangement has a double object. In the first place theupper edge of the wick is kept smooth and the fluid soaked up evaporatesfrom the inside of the wick only. Asmoking flame which would blacken themantle is avoided, as projecting points of the wick are prevented. Inthe second place the gases developed on the inside of the wick have awinding and consequently longer way to travel before they reach throughthe aperture f, and a more thorough mixing takes place with the airpassing the wick-case on the outside as well as on the inside.

In the arrangement shown in Fig. l the cap or casing it rests upon thewick and is screwed up and down with it, while in Fig. 2 the cap orcasing it rests upon a flange t' in the cap 61, and in this case thewick must be screwed up against the bent edge g of the cap or casing. I

The lamp is lighted after the part with the glass, glow-net, cap, andcap or casing It has been lifted so high that access is gained to thewick. When the said parts are again lowered and the wick screwed up, theflame is transformed into a Bunsen flame, which brings the net toincandescence.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is l. A burner for lamps of the character described,consisting in the combination with a wick-case, of a cap d, having aninwardlybent edge, a disk 6, arranged to form a circular space orinterval f, between its edge and the said edge of the cap in line withand above the upper end of a wick contained in the wick-case, and a capor casing h, arranged over the wick-case between the latter and the capd, and having an inwardly-bent upper edge 9, lying directly over theupper end of a wick, said edge 9, inclosing an annular space which is ofless diameter than that of the disk 6, whereby to cause the flame totake a circuitous passage from the wick through the space f, and thesaid cap h, being adapted to leave a space between edge g, and the upperend of the wick-case.

2. A burner for lamps of the character described, consisting in thecombination with a wick-case, of a cap d, having an inwardlybent upperedge, a disk 6, arranged to form a circular space or intervalf, betweenits edge and the said edge of the cap in line with and above the upperend of a wick contained in the wick-case, the cap or casing h arrangedover the Wick-case between the latter and the cap d, and having aninwardly-bent upper edge g, lying directly over the upper end of a wick,said edge g, inclosing an annular In testimony that I claim theforegoing as space which is of less diameter than that of my invention Ihave signed my name in presthe disk 6, whereby to cause the flame totake a circuitous passage from the wick through ence of two subscribingwitnesses. the space f, and said cap h being adjustable GEORG KRON. 5vertically by the wick to leave a space be- \Vitnesses:
